Problem with discs?

Ok guys....I'm somewhat of a newbie. Please bear with me. I’ve made 10 successful burns using Memorex DVD-R’s. I’m using DVDshink 3.2 and Nero 7 ultra. My problem is I just tried burning Serenity with Sony DVD-R’s and I’m getting a shut down with Nero. No matter what I try to burn to these Sony disc I keep getting a burn failed, But when I use a Memorex disc it works. Am I doing something wrong or is it the Sony discs? Help I spent $30/100 and already went through 6 discs!

did you buy those sony dvd-r's from bestbuy? however you have goten a bad pack of disc and maybe you can tell them back and exchange them for somemore or another brand. also what type of burner are you using?

I think you guys got the wrong idea here. first off Memorex is crappy media! don't use it.... those Sony disks are better quality and should do the job.....Some people had problems with Serenity:http://forums.afterdawn.com/thread_view.cfm/274615
or maybe your drive doesn't like the -R media! try +R media and booktype to DVD-ROMs if your drive allows it:

1. burning speeds: burn at 4x so there will be less writing errors (rule of thumb is to burn at half the rated speed of the disk--8X disk burn at 4x).
2. read manual for your stand alone player and use the disks that will play in your player. If your player is less than 2 yrs old then it should play the + or - R disks! I said SHOULD that's why you read the manual.
3. try booktyping your drive to DVd-ROM so it will make your +R disks more compatible to players. Read this:http://k-probe.com/bitsetting-booktype-faq.php
4. make sure that there are no finger prints or scratches on your disk that make it hard for the player to read the disk!
5. use good quality media (rule of thumb....buy the ones that are Made in Japan.) Verbatim is a top notch disk and is the only exception to this rule....some Verbatims are made in Taiwan and they are top notch!
6. and don't burn too close to the outer edge of the disk ..... which will make the disk unreadable! but using good media you will be able to burn close to the edge better than lesser quality media. Just in case I only burn no closer than 4400MB, so if you can set your programs to that, all the better!

follow these little tips of the trade and you'll have better success! good luck.

i have made close to 100 burn on memosux never really had problem with them. for the next 100 i bought verbs pretty much same price as memorex so why not go with known good media.just thought i would share my info.

Wait, saugmon it might not be the disc but NERO! I do have an error log but not sure what to post from it.
Did any actual burning take place? Look at the bottom for the discoloration from the burn. yes
What speed rate were those Memorex discs? 16x
What speed rate are the Sony? Probably 1x-16x. 16xI went back to my Memorex and burned both DVD's with no problem.
